EDGAR BURNl-IAH, OF SAN DIEGO, CALIFORNIA.

MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 447,040, dated February 24, 1891.

Application filed June 12, 1890- Serial No. 355,163. (No model.)

To aZZ whom it may concern:

Be it known that I, EDGAR W. BURNHAM, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Sheet-Music-Leaf Turners; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved music-leaf turner, which combines simplicity and cheapness of construction with great convenience, ease, and efficiency in use; and my invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a front elevation of my new and improved music-leaf turner. Fig. 2 is a perspective front view with the outer cover removed. Fig. 3 is a detail view of one of the sliding bars with its corresponding grooved roller, arm K, and connecting parts. Fig. 4- is a detail view on an enlarged scale of one of the grooved spools, and Fig. 5 is a detail view hereinafter referred to.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A indicates a bracket-frame constructed of suitable and very light material. Upon the upper part of this frame is secured in end brackets, as shown, a vertical shaft B, upon which are mounted the series of independent spools 0. Each of these spools is formed with the annular grooves C, which may be arranged, as shown, or formed one near each end of the spool.

D indicates a series of sliding horizontal bars, the ends of which are formed with the open slots D, in which fit the guide-brackets E, which are secured at their ends to the frame A and curve out to receive the slotted ends of the bar D, as shown in Fig. These sliding bars are separated and supported on anti-friction pins F, which pass through the brackets E, as shown.

Upon the frame A are centrally pivoted at G the operating rods or levers G, the lower ends of which extend down in convenient proximity to the keys of the piano or organ.

The upper end of each rod is formed with a short longitudinal slot G, through which a pivot-pin H passes into the sliding bar D,with which that rod is connected, as shown. A cord I is secured at its center to a small screw J in each grooved spool O, and is then given one turn around the spool and has its ends secured to the sliding bar D back of it on opposite sides of the spool-shaft B, preferably by passing its ends through apertures (Z in the bars and knotting their extremities.

To each spool O is secured a light horizontal arm K, to the outer end of which is adjustably secured a flexible strap L, which may be done by passing the upper end of the strap through a longitudinal open slot 7.; in-

t-he end of the arm and then screwing a threaded ring K on the threaded end of the arm, as clearly shown in Fig. 5 of the drawings. Upon the lower end of each flexible strap is secured an ordinary spring-clasp M.

An outer cover N covers the bars D and other working parts of the device from View, the lower ends of the operating-rods G extending down below the open lower end of the outer cover N in close proximity to the keys of the organ or piano.

The sheet-music or music-book is placed upon the rest N of the cover N, and is held in place by a tape or rubber O, which is secured at its ends, as shown, to the outer cover. The spring-elasps M are then caught on the upper ends of the several leaves to be turned, and the device is ready for use. lVhen a leaf is to be turned, the player merely touches with his finger the lower end of the proper 0perating-rod G, moving it to one side, the rod turning on its pivotal point, when its upper end will slide that bar D to one side and the cords I will turn the grooved spool C. The spool carries around with it its arm K, which through the flexible strap L with its end spring-clasp M, will at once turn the music-leaf over. The next leaf is turned by touching the next lever G, and so on for all the leaves, and by an opposite movement any or all of the leaves can be turned back, as required.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood.

It will be seen that my new and improved music-leaf turner is very simple, durable, and cheap in its construction and exceedingly con venient and efficient in its operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a music-leaf turner, the combination of the frame A, the horizontally-sliding bars D, supported thereon, the vertical shaft B, the series of grooved spools 0., mounted thereon and having the arms K, the flexible straps L, having the end clasps, the cords I, secured at their opposite ends to the sliding bars and passing around the grooved spools, and the "centrally-pivoted operating-rods G, having their upper ends pivotally connected to the sliding bars, substantially as set forth.

2. The combination of the frame A, the guide-brackets E, the sliding bars D, formed with the end slots, the bearing-pins F, on which the sliding bars rest, the vertical shaft B, the series of grooved spools C, mounted thereon and having the arms K, the flexible straps L, having the end clasps, the cords I, secured at their opposite ends to the sliding bars and passing around and secured to the grooved spools, and the centrally-pivoted operating-rrods G, having their slotted upper ends pivoted to the sliding bars, substantially as set forth.

In a music-leaf turner, the combination, with the movable spools O, of the arms D, secured thereto at their inner ends and formed at their outer threaded ends with the open slots 70, the threaded rings K, screwing on the slotted threaded ends of the arms, and the adjustable flexible straps L, having the'springclasps at their lower ends, substantially asaround and secured to the grooved pulleys,

the centrally-pivoted operating-rods G, having their slotted upper ends pivoted to the sliding bars, and the outer cover N, having the music-rest N and the music-retaining strap 0, substantially as set forth.

In testimony whereof I have afiixed my sig: nature in presence of two witnesses.
